Although we can preallocate a given number of elements in a vector, it is usually more efficient to define an empty vector and add elements to it (as we'll learn how to do shortly).

虽然可以对给定元素个数的 vector 对象预先分配内存，但更有效的方法是先初始化一个空 vector 对象，然后再动态地增加元素（我们随后将学习如何进行这样的操作）。

AIM: To construct the eukaryotic expressing vector of human cbl and test its expression in African green monkey kidney cell line COS 7. METHODS: Human cbl gene tagged with flag was amplified from pEFHAcbl plasmid by PCR. The product was cloned into pGEM T easy, sequenced and then subcloned into eukaryotic expressing vector pcDNA3.1.

Boys are abler to understand the abstract geometrical patterns than girls do.

与女孩相比，男孩在理解抽象几何图形方面能力更强。

Several combining with middle school mathematics teaching Abstract: combining the number is the number of more abstract corresponding relation and the geometrical graph, combine to solve the problem of abstract concepts to materialize and intuitive, intuitive, abstraction, and systematic problem to reduce the difficulty of the problem, and to help students thinking transformation and training students' ability.

数形结合与中学数学教学摘要：数形结合就是把较为抽象的数量关系和与其对应的几何图形相互结合起来解决问题，使抽象的概念直观化、具体化，使直观的问题系统化、抽象化，从而达到降低难题的难度、帮助学生思维转换、培养学生能力的作用。

A new digital measure method was presented based on the three coordinate measuring machines. Compensation of sensor radius, establish part's measure reference frame, the best measuring layout and mix programmed scanning all those not only enhance measure precision and increase efficiency of scanning measure, but also the data can image geometrical characteristic of complex surface. The method was illuminate by a sample, and the digital data of the surface adumbration are obtained at last
